[analyzer] Restrict ObjC type inference to methods that have related result type.

This addresses a case when we inline a wrong method due to incorrect
dynamic type inference. Specifically, when user code contains a method from init
family, which creates an instance of another class.

Use hasRelatedResultType() to find out if our inference rules should be triggered.
